2024-01-02ARM: sun9i: smp: fix return code check of of_property_match_stringStefan Wahren
of_property_match_string returns an int; either an index from 0 or greater if successful or negative on failure. Even it's very unlikely that the DT CPU node contains multiple enable-methods these checks should be fixed. This patch was inspired by the work of Nick Desaulniers.

2023-12-29x86/kexec: fix incorrect end address passed to kernel_ident_mapping_init()Yuntao Wang
kernel_ident_mapping_init() takes an exclusive memory range [pstart, pend) where pend is not included in the range, while res represents an inclusive memory range [start, end] where end is considered part of the range. Passing [start, end] rather than [start, end+1) to kernel_ident_mapping_init() may result in the identity mapping for the end address not being set up. For example, when res->start is equal to res->end, kernel_ident_mapping_init() will not establish any identity mapping. Similarly, when the value of res->end is a multiple of 2M and the page table maps 2M pages, kernel_ident_mapping_init() will also not set up identity mapping for res->end. Therefore, passing res->end directly to kernel_ident_mapping_init() is incorrect, the correct end address should be `res->end + 1`.

When detecting an error, the current code uses kexec_dprintk() to output log message. This is not quite appropriate as kexec_dprintk() is mainly used for outputting debugging messages, rather than error messages. Replace kexec_dprintk() with pr_err(). This also makes the output method for this error log align with the output method for other error logs in this function. Additionally, the last return statement in set_page_address() is unnecessary, remove it.

2023-12-29arch/mm/fault: fix major fault accounting when retrying under per-VMA lockSuren Baghdasaryan
A test [1] in Android test suite started failing after [2] was merged. It turns out that after handling a major fault under per-VMA lock, the process major fault counter does not register that fault as major. Before [2] read faults would be done under mmap_lock, in which case FAULT_FLAG_TRIED flag is set before retrying. That in turn causes mm_account_fault() to account the fault as major once retry completes. With per-VMA locks we often retry because a fault can't be handled without locking the whole mm using mmap_lock. Therefore such retries do not set FAULT_FLAG_TRIED flag. This logic does not work after [2] because we can now handle read major faults under per-VMA lock and upon retry the fact there was a major fault gets lost. Fix this by setting FAULT_FLAG_TRIED after retrying under per-VMA lock if VM_FAULT_MAJOR was returned. Ideally we would use an additional VM_FAULT bit to indicate the reason for the retry (could not handle under per-VMA lock vs other reason) but this simpler solution seems to work, so keeping it simple.

2023-12-29powerpc/ps3_defconfig: Disable PPC64_BIG_ENDIAN_ELF_ABI_V2Geoff Levand
Commit 8c5fa3b5c4df ("powerpc/64: Make ELFv2 the default for big-endian builds"), merged in Linux-6.5-rc1 changes the calling ABI in a way that is incompatible with the current code for the PS3's LV1 hypervisor calls. This change just adds the line '# CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 is not set' to the ps3_defconfig file so that the PPC64_ELF_ABI_V1 is used. Fixes run time errors like these: BUG: Kernel NULL pointer dereference at 0x00000000 Faulting instruction address: 0xc000000000047cf0 Oops: Kernel access of bad area, sig: 11 [#1] Call Trace: [c0000000023039e0] [c00000000100ebfc] ps3_create_spu+0xc4/0x2b0 (unreliable) [c000000002303ab0] [c00000000100d4c4] create_spu+0xcc/0x3c4 [c000000002303b40] [c00000000100eae4] ps3_enumerate_spus+0xa4/0xf8 Fixes: 8c5fa3b5c4df ("powerpc/64: Make ELFv2 the default for big-endian builds") Cc: stable@vger.kernel.org # v6.5+ Signed-off-by: Geoff Levand <geoff@infradead.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/df906ac1-5f17-44b9-b0bb-7cd292a0df65@infradead.org

2023-12-24arm64: dts: rockchip: Fix rk3588 USB power-domain clocksSam Edwards
The QoS blocks saved/restored when toggling the PD_USB power domain are clocked by ACLK_USB. Attempting to access these memory regions without that clock running will result in an indefinite CPU stall. The PD_USB node wasn't specifying this clock dependency, resulting in hangs when trying to toggle the power domain (either on or off), unless we get "lucky" and have ACLK_USB running for another reason at the time. This "luck" can result from the bootloader leaving USB powered/clocked, and if no built-in driver wants USB, Linux will disable the unused PD+CLK on boot when {pd,clk}_ignore_unused aren't given. This can also be unlucky because the two cleanup tasks run in parallel and race: if the CLK is disabled first, the PD deactivation stalls the boot. In any case, the PD cannot then be reenabled (if e.g. the driver loads later) once the clock has been stopped. Fix this by specifying a dependency on ACLK_USB, instead of only ACLK_USB_ROOT. The child-parent relationship means the former implies the latter anyway.
